We look at the division of 800865 by 65 
Let's see how many times 65 fits into 800865.

Advancing to step 1:
65 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 65

Going ahead to step 2:
65 can be fit into 80 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 65 from 80 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 65

Step 3:
The number 65 fits into 150 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 12.0
If we take 130 away from 150, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 65

Going ahead to step 4:
The number 65 fits into 208 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 195 from 208 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 65

On to step 5:
If we divide 136 by 65, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1232.0
Subtract 130 from 136 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 65

Moving on to step 6:
65 can be fit into 65 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 12321.0
Subtract 65 from 65 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 65, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12321.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 65, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12321.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 12321.0, with a leftover of 0.0.
